Which bird family is described as having large, broad wings, short tails, with spare and labored wing beats?

The bird family characterized by having large, broad wings, short tails, and a pattern of spare and labored wing beats is indeed the Buteos. This group of raptors, commonly known as buzzards or hawks, often includes species like the Red-tailed Hawk. Their large wings provide the ability to soar efficiently, while their relatively short tails help with stability during flight. Buteos typically have a more leisurely flight style compared to other raptors, which is evident in their labored wing beats that come into play as they soar and glide in search of prey or while scouting their territory.

This adaptation allows them to maximize energy efficiency while flying over large areas, which is crucial for hunting and migrating. The physical characteristics of Buteos distinguish them from other raptor families, such as Accipiters, which have longer tails and more agile flight patterns suitable for hunting in dense forests, or Falcons, known for their pointed wings and rapid, powerful flight. Harriers, on the other hand, are recognized for their long wings and tails, as well as a different flying style that enables them to navigate low over ground.
